Thomas Mario Haas (born 3 April 1978) is a German former professional tennis player. He competed on the ATP Tour from 1996 to 2017. After breaking into the world top 100 in 1997, and reaching a career-high singles ranking of world No. 2 in May 2002, his career was interrupted by injuries: Haas twice dropped out of the world rankings due to being unable to play for twelve months. He returned to world No. 11 in 2013, after reaching the quarterfinals at the French Open for the first time in his career.

Sabine Katharina Lisicki (born 22 September 1989) is a German tennis player who turned professional in 2006. Her breakthrough was in 2009 when she reached the quarterfinals of the Wimbledon Championships, and also won her first title on the WTA Tour, at the Family Circle Cup.

In March 2010, she suffered an ankle injury at the Indian Wells Open that kept her out of competition for five months and saw her fall out of the top 200. Lisicki rebounded in 2011 and won the Eastbourne Classic before entering the Wimbledon Championships as a wildcard and going on to reach the semifinals, where she lost to Maria Sharapova.
